W. C. TROUT WALKING BEAM Filed Nov. l, 1930 Waltgr- @Trout- JWMM Patented .J an. 5, 1932 UNITE-D. STATE- slp 1,840,066l f e WAmEn c. TROUT, y.or mfrKIN,-TmrasQy l Application yiled November 1, ,"193'0r` Serial No. 492,736.

My invention relates to an improvement in walking beams such as are employedin deep well operations in pumping or standard tool drilling. r

5 It is an objectof the inventionto provid a walking beam of strong and sturdy con-y struction and which may be easily formed from ordinary structural steel. l

It is another object of the invention to provide an attachment at the ends ofthe beam whereby the same may be connected either to.

a pitman or to a rod hanger, as the case may be, in the operation of the beam.

The invention consists also in the particu- 15 lar arrangement whereby the operating member, either the pitman or the rod connection, may be pivoted to a walkingbeam in an expeditious manner and with a strong and substantial support. l

In the drawings herewith, Fig. 1 is a top plan view of a walking beam embodying my invention. y

Fig. 2 is a side elevation thereof.

Fig. 3 is a longitudinal section through the end of the beam showing the inner side of one of the plates. v

Fig. 4 is an end View of the beam, the lower righthand portion being in section.

The beam which I employ ispreferably of 30 I-beam construction. Said beam 1 is formed of the proper length and adjacent the ends thereof the lower side is` beveled upwardly as indicated in dotted lines atQ.y Between the ends the beam is reenforced yat intervals by transverse members 3 of angle iron or similar structural steel fitting between the upper web 4 and the lower web 5 of the beam. I

have shown two of these closely adjacent the center of the beam and above the bearing plate 6, which has the laterallyk extending Cul trunnions 7 thereon, by means of which the beam may be supported for rocking upon the Sampson post, not shown.

At the ends of the beam I secure by welding or otherwise two opposite plates 8. Said f plates are squared at their upper ends to fit against the side of the beam and the lower end is beveled forwardly and extends belowy the level of the beam.YV These two plates are Set A i .It willbe notedthat I between ythe beam and any ordinary operai directly oppositeeach other and have openings 9ftherethroughto receive a bolt 10. j

Immediately belowthe openings `9 inthe plates I form a bearing socket 11. The form of 'socket shown is asemi-,circular member welded-to theinner side of the iplate 8 sothat thelupperA recess 12-may forma socket toreceive f a bearing vsleeve 13.y Saidbearing l'slee'e`ve,'fask 'shown finFig. 4, is of the proper length to fit ybetween theftwoside plates Sand e0 Vhas la longitudinal opening-to receive the -bolt 10by means of which said sleeveis secured 1n positionV supported within vthe f bearing sockets 12. f v have formed plates 1,65 8 'with the bearing members f thereon `at each end of the beam anditris to :be noted thatthe bearing sleeve L413 may form a support rvfor arod hanger shown fat 14 lin" Fig. ,2, or it mayserv'e as a pitman bearing for thepitman'xlat th'e opposite end of the beam.

Therefore, a beam constructed in this manner has at either end a strong and substantial bearing whereby attachment may be made tive device connectedtherewith.

My walking beam is exceedingly simple in construction but is strong and adapted to un-k dergo theheavy strains to `which such beams are subjected and has a substantial bearing whereby connections `may bey made thereto with a minimum of difficulty. The invention resides inthe extreme simplicity and strength yof the bea-m and its ready adjustabilityfor vany ordina-ry use.

` What I claim as new is:

1. A walking beam including an I-beam, a

` rock shaft midway of the ends thereof, means transversely of said beam to reenforce ther same,rend plates secured to said beam on opv positey sides and depending below the lower side thereof, said plates having openings therein to receive a transverse bearing bolt, aV bolt therein, a bearing on said bolt, and means on'said plates` to support said bearing. #95 2. Awallring beam including an I-beam,4 a rock .shaft midway of the ends thereof, means transversely of said beam to reenforce thev same, end plates secured to said beam on opposite sides and depending below the low- 1100 er side thereof, said plates having openings therein to receive a transverse bearin bolt, a bolt therein, a bearing on said bo t, and means on said plates to support said bearing comprising upwardly presented semi-circular seats formed rigidly on said plates.

3. A walking beam including an I-beam, a. rock shaft midway of the ends thereof, means transversely of said beam to reenforce the same, end plates secured to said beam on opposite sides and depending below the lower side thereof, said plates having openings therein to receive a transverse bearing bolt, a bolt therein, said bolts being below the lower side of said beam, sockets formed on the inner sides of said beam, a bearing member journalled in said sockets, and means to retain said bearing member in position therein.

4. A walking beam of structural steel, a

pair of plates secured to the sides of said f beam at each end thereof and projecting below said beam, socket members formed rigidly on the inner sides of saidplates, a bolt connecting said plates and a bearing sleeve on said bolt supported in said socket members.

5. An I-beam having its ends tapered upwardly, a pair of plates on each side of the tapered ends, said plates depending below said beam, bearing sockets formed on the inner sides of said plates below said beam, a bearing sleeve in said sockets, and a transverse bolt through said sleeve.

In testimony whereof I hereunto aflix my signature this 27th day of October, A. D.
